I found a thread on repeated artists:

And this regular expression  
`$regexp($replace(In My Arms [Crumbling Down Mix] Crumbling Down Mix,[,,],),'(.+?)/\1','$1')`  
results in  
`"In My Arms Crumbling Down Mix"`  
which has actrually 2 blanks in front of the "crumbling". So it should be easy to replace those with a [if required. The] can be added in the regular expression already as text constant.
